查询结果中包含null的值，对于一些数字或boolean包含null，定义该项时必须使用wrapper类型，而不能是primitive类型，例如使用Integer而不能是int,Boolean而不能是boolean否则会抛出exception 

导致原因： 数字型字段值为空. 
解决方法： 
补充下，主要是数据库中的long ，int等原始数据类型为null，如果hibernate映射文件的字段类型为long，由于null不能赋值给原始类型，所以报错。解决方法1：让字段不为空，方法2：把映射文件的字段改为对象。如long　改为 Long ,int 改为Integer， 
double改为 Double 
例子：   
(原先) 
   <property name="cityid" type="long" > 
            <column name="CITYID" precision="22" scale="0" /> 
        </property> 
改为： 
        <property name="cityid" type="java.lang.Long" not-null="true"> 
            <column name="CITYID" precision="22" scale="0" />
